Enhancing low‐temperature SCR deNOx MnCe catalyst based on rice husk char by KOH and H₃PO₄ activation

BACKGROUND It is of great significance industrially to find cheap materials as low‐temperature selective catalytic reduction (SCR) catalyst support. Pyrolyzed rice husk char (RC) is not only cheap, but also has the characteristics of high porosity, large SSA and good adsorption. Therefore, there is emerging interest in RC as an SCR support. The present contribution is a comparative study of low‐temperature SCR manganese–cerium (MnCe) catalysts...
